To simplify the wiring diagram there is shown in the accompanying drawings a single unit comprising sixteen totalizers, however as many such units as desired may be suitably connected to the power drive shaft and inserted into the wiring hook up, any unit being adapted to be selectively operated, as will be described later.
As the best means of describing the circuit and operations of the machine we will 90 till till

take the value 756 and first add the same into a given totalizer, taking for this purpose totalizer eight.
As previously stated, there are sixteen totalizers in each unit, and any desired number of units, therefore, as a means of identification, the various units will be lettered A, B, C etc. and the totalizers numbered from one to sixteen, that is, the totalizers of unit (A) will be designated as A1, A2, etc., of unit (13) B1, B2, etc.
To add the above value 756 into the accumulators of totalizer A1 1, select the unit A by depressing and releasingthe unit sclecting key A (Figs. 1, 5, 9 and 15), there being a unit selecting key A, B, C etc. for each unit said keys being adapted to operate by upward spring movement, upon release of a detaining latch in accordance with the disclosure set forth in patent application Serial No. 518,935.
[)peration of the unit selecting key A will cause the cross-tree member 1 (Fig. 15), pivotally mounted thereon, to bridge the pins 2 and 3, to thereby extend the positive circuit from the positive service line 4 through leads 5 and 3 1 1) to the normally closed points 8 and 9 of a relay switch member 'i' and thence, through the lead 10, to the positive poles of a series of digit magnets 11 (Figs. 14, 19 and 20). There are nine of said magnets in each denominational order, and ten denominational orders, as will be more fully described later. The circuit from lead 5 is also extended, through lead 12, to the positive poles of a series of totalizer selecting magnets 13 (Figs. 14:, 18 and 20), there being 32 of said magnets, located sixteen on either side of the machine, as will be described later.
Having thus selected the desired unit, by closing the positive circuit to the same, the desired totalizer, number eight, is selected in the following manner:
A. switchboard member 14 (Figs. 1, 2, 3 and 10), suitably supported upon the rear framing of the typewriter, as shown, is composed of sixteen groups of circuit pins 15, each group adapted to control the circuits to a corresponding totalizer, as will hereinafter be described.
An indicator strip 16 (Figs. 1 and 11), mounted upon the forward edge of the carriage 17, is divided into sixteen equal spaces, corresponding to the sixteen groups of circuit pins in the switchboard 14.
To select any desired totalizer the carriage 17 is shifted to the space corresponding to the preceding totalizer, that is, to select totalizer number eight the carriage is shifted to bring the space seven to indicating position, as read through the sight opening 18 (Fig. 1).
The tabular key 19 is then operated, whereupon the carriage will escape toward the left in the usual manner until stopped in the regular way by means of the tabulator stops 20 (Figs. 1 and 2). The tabulator stops 20 are spaced at definite intervals, corresponding to the spacing of the group of pins 15, and will now cause the carriage to be positioned so that a series of wipers 21, (Figs. 2, 13 and 28), mounted upon the rear surface of an insulated arm 22, supported upon the cross-rod 23 of the carriage, will be in contact with the right hand or highest Order of the pins 15 in group eight.
There are thirteen of said wipers 21, mounted one above the other as shown in Figs. 2 and 13, each wiper being connected by means of pins 23 to corresponding wipers 24 mounted upon the forward surface of the arm 22 and having engagement with corresponding level contact strips 25 of a switchboard member 26 (Figs. 12 and 13).
Note that the strips 25 of Fig. 13 are reversed for simplicity of illustration.
The top level wiper 21 now being in contact with a contact strip 27 of switchboard 1%, will extend a negative circuit line from the negative poles of the number eight totalizer selecting magnets 13 to one terminal 28 (Fig. 15) of a cam-controlled switch member 23 (Figs. 15 and 22) through leads 30 strip 27, wiper 21, wiper 24, contact strip 25, and lead 31. There is a contact strip 2? for each pair of totalizer selecting magnets 13 as shown.
As shown in Figs. 10 and 13, the circuit pins 15 of switchboard 14 are arranged in ten vertical columns, there being ten pins in each column, arranged according to digit values from 0 to 9, the top level being zero, the next level one, etc. The left hand col umn of pins control the circuits for the lowest or units order, the next right hand column the tens, etc.
The carriage is now brought to the proper denominational position by means of denominational keys 131 (Figs. 1, 2, 6 and 15), in the following manner. Depress the denominational key 431 corresponding to the number of places or denominations that occur in the value to be added, in this instance the number 3 key, since there are three denominations to the value (756).
Depression of the number three denominational key 431 will cause said key to contact the points 32 and 33 of a switch member 34 corresponding to said key, there being in a l nine keys and nine corresponding switches.
As shown in Fig. 15, the contacting of points 32 and 33 of switch 34 will extend the negative service line 35 to the negative pole of a corresponding solenoid 36 (Figs. 2, 3 and 15), there being a solenoid 36 for each denominational key. Depression of a denominational key will also cam a slide member 37 toward the right and an insulated tip 38,
mounted thereon, will cause the contacting of points and 41 of a switch member 42, to thereby extend the positive circuit from the main service line 4 to the positive poles of solenoids 86 and, the negative circuit to the number 3 solenoid being closed as previously described, said solenoid will become energized and attract its plunger 43.
The plungers 43 are pivotally connected to one end of a series of denominational positioning levers 44 (Figs. 1, 2, 3, 4 and 15), loosely mounted upon a shaft 45, extending transversely of the machine and suitably supported in the casing, as shown. There are ten denominational positioning levers 44, corresponding to the ten solenoids 36, there being ten denominational places provided in the machine.
Since, as previously described, the tabulating key 19 positioned the carriage in the highest denominational order, only nine denominational keys are required. However, there are ten solenoids and ten corresponding carriage positioning levers 44, the tenth or 7 highest order lever being needed when totals are being taken, as will hereinafter be described.
The particular carriage positioning lever 44 operated by its corresponding solenoid 36 is adapted to position the carriage to bri'tg the wipers 21 of arm 22 into contact with the corresponding denominational order of pins 15 in the selected group eight, in the following manner:
The attraction of plunger 43 of the number three solenoid, as previously described, will rock the corresponding positioning lever 44 counter-clockwise about shaft 45, to thereby advance the end 46 of said lever to a position overlying the path of movement of a series of equally spaced projections 47, mounted upon the carriage escapement rack 48.
The above described movement of the positioning lever 44 will also cause the rear surface of said lever to engage a cross-rod member 49 (Figs. 2, 3, 4, and 15), extending transversely of the levers 44 and supported at either end by the links 50 and 51, said links being pivotally mounted upon the pins 52 and 53, as shown in Fig. 4.
The engagement of lever 44 with rod 49 will rock said rod rearwardly, to cause an insulated finger 54, fast to same, to engage a switch member 55 and cause the contacting of points 56 and 57 of said switch (Fig. 15). The contacting of points 56 and 57 of switch 55 will close the circuit from the main positive service line 4 to the positive pole of a solenoid 58 (Figs. 2A and 15), through the following leads: 59, 60. 61. the normally closed contacts 62 and 68 of a relay switch, member 64,1ead 65,points 56 and 57 of switch 55 nd lead 66. The negative circuit of said solenoid being continuous to the main negative service line 35, through leads 67, 68, the
contact points 69 and 70 of a cam-controlled switch member 71, and leads 72 and 7 3, said solenoid will become energized and attract its plunger 74.
An arm 75, extending through a slotted opening in the plunger 74, is pinned to a shaft 76, mounted in the casing of the machine as shown. Fast tothe opposite end of shaft 76 is a lever 77, extending beneath the carriage escapement rack 48 as shown in Figs. 2 and 4.
The attraction of plunger 74 will cause a pin 78, fast to said plunger, to engage the arm 75 and rock the shaft 76, to thereby cause lever 77 to raise the carriage escapement rack, whereupon the carriage will again escape toward the left, until stopped by means of one of the projections 47 coming in contact with the advanced end 46 of the denominational stop lever 44.
As illustrated diagrammatically in Fig. 15, when the end 46 of a positioning lever 44 is advanced it will be extended through a slotted aperture 79 of a slide member 80, slidably mounted upon a guide bracket 81 as shown in Figs. 2 and 4. As the projection 47 of rack .48 strikes the end 46 of lever 44, it will thrust said lever slightly sideways, until stopped by the edge 82 of the guide bracket 81. This slight lateral movement of the lever 44 is imparted to the slide member 80, and an insulated pin 83 mounted thereon will cause the contacting of points 84 and 85 of a switch member 86. The contact point 85 of said switch is connected directly through leads 66 and 59 to the positive service line 4 and will therefore extend said circuit through contact 84 and lead 86 to the positive pole of relay member 64, and the negative pole of said relay being connected to the negative service line 35, through leads 87, 67,- 68, contact points 69 and 70 of switch 71, lead 72 and lead 78, said relay will become energized and attract its armature 88, thereby breaking the circuit to the solenoid 58, while at the same time contacting the points 89 and 90 of said relay 64.
The circuit thus being broken to solenoid 58, the same will become de-energized'and will release its plunger 74, to thereby allow ire-engagement of the carriage escapement rack 48 with the usual escapement mechanism, the carriage now being positioned in the proper denominational position, that is, with the wipers 21 contacting with the third left hand column of pins 15, corresponding to the third denominational order. The contacting of points 89 and 90 of relay 64 is for the purpose of re-establishing the positive circuit to said relay, which was also broken when the points 62 and 63 were disengaged. Thus the circuit to solenoid 58 will remain broken, while the relay member 64 will remain energized until its circuit is broken in the manner hereinafter to be described.
